I’ve noted on other postings that I’ve bought into part of the old German school of education which taught that to educate the mind; you had to also exercise the body. The two were intertwined; ignoring one came at the detriment of the other. 19th Century educational advances, such as the kindergarten and gymnasium, came from Germany and are still part of today’s curriculum.

I’ve agreed with the theory because personal and anecdotal evidence. Here is a study where the results are essentially saying, “A healthy body leads to a healthy mind”. Technical results are here: http://www.ncbi.nlm.nih.gov/pubmed/18768414 highlights and practical details are here: http://www.realage.com/ct/shape-up-slim-down/workouts/tip/7570
 
After just 6 months of doing an extra 20 minutes of exercise daily (on top of the physical activity done normally), a group of adults experiencing slight losses in memory and verbal fluency saw improvements. More good news: The exercise didn’t have to be terribly taxing. Not only did walking work but so did swimming and ballroom dancing.

Even better, the improvements persisted for 12 months after the study ended, and some benefits lasted up to 18 months. The research suggests that exercise may help delay Alzheimer’s in at-risk adults -- people who have mild cognitive decline.

So, go take a walk, its good for your brain.
